SOLVED: del78 no. 144 by pnegyesi: Homemade vehicle running on compressed air build by Karl Laa

[pnegyesi]

His name was Peter Vrbata
"A compressed air car was one of the most admired inventions at the opening of the iENA 80 yesterday.
An Austrian researcher installed several compressed air bottles on a chassis. Via valves the air is conducted to the compressed air motors which drive the vehicle through transmission. Without gasoline and exhaust fumes the 0.5 horse power car has a range of
approximately 70 km or one hour of operation. The empty compressed air bottles can be refilled with a compressor which will be plugged into an electrical socket. The price per kilometer is 1.5 Pfennigs. It is intended to build a standard size car at a later date."

Yes, I've just found an article about it

yes You found the vehicle but as You can see on Oguerrerob's article scan Peter Vrbata is the name of photographer not an inventor of this vehicle.
I have a different name for him.
If I am wrong please prove it

[Oguerrerob]

Did this inventor build other car?

[pnegyesi]

Karl Kraft?

[del78]

Karl Kraft?

You are close, You need to find the surname

[pnegyesi]

was he Karl Laa by any chance?

[del78]

was he Karl Laa by any chance?

You are closer than You think, change one letter is surname
it is locked for You

I would love to, but that was his name in the patent:
"Motor vehicle, especially small vehicle ,
The innovation relates to a motor vehicle, in particular a small motor vehicle, with at least one motor driven by compressed air, the drive shaft of which is mechanically operated"

by Karl Laa, 2104 Spillern, Niederösterreich. Filed in 1980

so this must be Karl Laa
in eighties polish magazines weren't so good in translations
2 points for You pnegyesi
original article (in polish):

Another BH puzzle solved. Yeehaw

Some more photos from a recent article covering Karl Laa and his car running on compressed air. For testing purposes the drivetrain was fitted into a Johnny Panther small car

Machine translated text:
A manually operated multi-way valve was responsible for controlling the air supply to the two Atlas Copco turbines, which, each coupled to a rear wheel, provided the drive. To make the vehicle independent of "gas stations", a dynamo and a compressor were also installed in the small car. LAA used the "exhaust air" from the turbines to drive a dynamo, which in turn generated electricity to operate a compressor built into the small car to charge the tanks. The dynamo was also mechanically coupled to the chassis on every downhill journey and provided energy for the compressor - to charge the tanks! (Today, in the case of e-cars, this is called "recuperation". The energy generated when braking is used to recharge the battery). The tanks could therefore be "charged" even while driving. At this point, many questions about the system remain unanswered, which the inventor, Karl LAA, can unfortunately no longer answer due to his age and illness. The four compressed air tanks installed in the small test vehicle, each with a loading capacity of 100 liters of compressed air (from Randeck near Gresten, Lower Austria), enabled a range of around 70 km in hilly terrain, or around 1.5 hours of driving time on flat land. The top speed was just under 70 km/h.

Though the system was well received both in Austria and outside the country too, eventually LAA gave up the experiments.
